I uploaded workflow_ng 1.6 to my site and found, after resetting the USPS quotes did get reasonable quotes! One problem I am asking for quotes for both parcel post and priority mail. The parcel post quote is always the higher of the two.

Also, once I do select the shipping method and click on the review checkout button, I am presented with a list of 22 error messages all from line 244 of ubercart/uc_store/includes/simplexml.php. This is followed by a message telling me that I didn't select the proper shipping method.

The checkout process works well with the flatrate quote method, except that the review order page always selects the default flat rate shipping even when the product has its own shipping rate.

I'd really, really like to see this fixed and am happy to do some testing with modified code.
